In case you didn't know, the Panthers have sort of adopted Spacey, 56, as the team's unofficial mascot. Whenever a player performs really well during a winning game, they're handed a blue sweatshirt with Spacey's head floating on it.

It has been dubbed the "Spacey in Space" sweatshirt and the actual meaning behind it remains a mystery.

The only one in on the team's inside joke is Spacey himself. He tweeted in December, "Only I really know what #SpaceyInSpace means. Hope it continues to bring good luck!"

Still, Spacey sported his own blue sweatshirt Saturday during the game. Masks featuring Spacey were even handed out inside the BB&T Center in Sunrise, Florida, to fans.

After the game, the Oscar winner stopped by the locker room to greet the team and take pictures, of course. In a photo posted to Instagram, Spacey said to the team: "Thank you @flapanthers and all the fans for such a wonderful welcome tonight."
